Abstract: A device may receive a power demand for a load and a weather forecast for a time period. The device may determine a first supply of power available from a photo-voltaic (PV) installation for the time period based on the weather forecast. The device may determine a power deficit for the time period based on the power demand and the first supply of power. The device may determine a first cost associated with utilizing a second supply of power available from a battery and a second cost associated with utilizing a third supply of power available from an engine for the time period. The device may determine a power source to overcome the power deficit based on the first cost and the second cost and may cause the PV installation and the power source to supply power to satisfy the power demand for the load.

Abstract: A rig management system is disclosed. The rig management system may be configured to receive information to be used to control shifting of a transmission to prevent cavitation during use of the hydraulic fracturing rig. The rig management system may be configured to determine a flow rate for a pump based on the information. The rig management system may be configured to determine an output torque of the transmission based on the flow rate. The rig management system may be configured to determine a transmission gear for the transmission based on the output torque and a fuel consumption map, wherein the fuel consumption map identifies a respective fuel consumption rate for different combinations of transmission gears and output torques. The rig management system may be configured to cause the transmission to shift into the transmission gear after determining the transmission gear.

Abstract: A rig management system is disclosed. The rig management system may gather, from a set of sensors, data that includes: vibration data related to vibration of a valve associated with a pump of a hydraulic fracturing rig during operation of the pump, and pump speed data related to a speed of the pump during operation of the pump. The rig management system may process the data to identify a trend related to the vibration data, wherein the vibration data has been normalized based on the pump speed data. The rig management system may determine a remaining useful life of the valve based on the trend and threshold data that identifies a set of thresholds related to the vibration of the valve. The rig management system may determine that the remaining useful life satisfies a threshold. The rig management system may schedule an operation to be performed on the valve.

Abstract: A method may include receiving power supply-related information, cost-related information, power demand-related information, and operational priority or site configuration-related information associated with hydraulic fracturing rigs. The hydraulic fracturing rigs may be each associated with a fuel consumption component or an emissions component. The method may further include receiving operational data and determining operational parameters based on the operational data and emissions output predictions for the hydraulic fracturing rigs. The method may further include outputting the operational parameters to a computing device or a controller. The method may further include, based on outputting the operational parameters, receiving operational feedback data and determining whether to modify the operational parameters. In addition, based on the outputting, the method may include determining whether to modify the operational data based on determining to not modify the set of operational parameters and modifying the operational data based on determining to modify the operational data.

Abstract: A system may determine configuration information associated with a power system for a work site that includes one or more power sources. The system may determine respective operation parameters of the one or more power sources and one or more performance criteria associated with the power system. The system may determine a baseline operation plan for the power system. The system may identify an optimization analysis technique and may process, using the optimization analysis technique, the configuration information associated with the power system, the respective operation parameters of the one or more power sources, and the one or more performance criteria associated with the power system to generate the optimized operation plan for the power system. The system may cause, based on the baseline operation plan for the power system and the optimized operation plan for the power system, one or more actions to be performed.
